Reporting ATV crash incidents

An ATV crash incident is any incident (regardless of the number of vehicles involved) that results in a fatality or an injury that requires medical treatment by a physician.

Wisconsin law requires every ATV operator involved in a crash incident to report the incident without delay to law enforcement officials. In addition, within 10 days of the incident, the operator must submit a written report on Form 4100-174 [PDF] to the Department of Natural Resources.
